Unintended Perinatal Health Consequences Associated With a Swedish Family Policy.

Importance: The 1980 and 1986 Swedish so-called speed premium policies aimed at protecting parents' income-based parental leave benefits for birth intervals shorter than 24 and 30 months, respectively, but indirectly encouraged shorter birth spacing and childbearing at older ages, both risk factors for several perinatal health outcomes. Whether those policy changes are associated with perinatal health remains unknown.

Objective: To evaluate the association between the 1980 and 1986 speed premium policies and perinatal health outcomes.

Cardiovascular Disease and Risk Factors in Individuals With a History of Out-of-home Care.

Background: Exposure to childhood out-of-home care (foster family and residential care) is associated with an increased risk of ill-health and disability in adulthood, but the risk for cardiovascular disease has not previously been studied longitudinally.

Methods: This was a national cohort study generated from linkage of a range of population-based registers, resulting in a national cohort of 881 731 of whom 26 310 (3.0%) had a history of out-of-home care.

Narcotic offences and drug use disorders among young refugees in Norway.

Aims: We examined the patterns of healthcare utilisation for drug use disorders (DUDs) and charges related to narcotics among young refugees in Norway considering the role of sex, country of origin and condition of arrival (accompanied versus unaccompanied minors).

Methods: Based on national registers, sex-stratified Cox regression models were used to estimate hazard ratios to assess the risk of being charged with a narcotics offence and the use of healthcare services related to DUDs. The sample consisted of 15,068 young refugees and 573,241 young Norwegians born in Norway to two Norwegian-born parents.

Labour market marginalisation in young refugees and their majority peers in Denmark and Sweden: The role of common mental disorders and secondary school completion.

Background: Due to the circumstances of their early lives, young refugees are at risk of experiencing adverse labour market and health outcomes. The post-settlement environment is thought to play a decisive role in determining how this vulnerability plays out. This study compared trends in labour market marginalisation in young refugees and their majority peers during early adulthood in two national contexts, Denmark and Sweden, and explored the mediating role of common mental disorders and secondary school completions.

Climate Change and Child Health Inequality: A Review of Reviews.

There is growing evidence on the observed and expected consequences of climate change on population health worldwide. There is limited understanding of its consequences for child health inequalities, between and within countries. To examine these consequences and categorize the state of knowledge in this area, we conducted a review of reviews indexed in five databases (Medline, Embase, Web of Science, PsycInfo, Sociological Abstracts).

Parental psychiatric morbidity related to experiences of war and trauma has been associated with adverse psychological outcomes for children. The aim of this study was to investigate parental post-traumatic stress in relation to psychiatric care utilization among children of refugees with particular attention on the child's own refugee status, sex of both child and parents, and specific psychiatric diagnoses. This was a register study in a population of 16 143 adolescents from refugee families in Stockholm County born 1995-2000 and followed between 2011 and 2017 (11-18 years old).

Importance of living arrangements and coparenting quality for young children's mental health after parental divorce: a cross-sectional parental survey.

Background: Parental separation has been associated with adverse child mental health outcomes in the literature. For school-aged children, joint physical custody (JPC), that is, spending equal time in both parents' homes after a divorce, has been associated with better health and well-being than single care arrangements. Preschool children's well-being in JPC is less studied.

Unintended health consequences of Swedish parental leave policy (ParLeHealth): protocol for a quasi-experimental study.

Introduction: Sweden has long been praised for a generous parental leave policy oriented towards facilitating a gender-equitable approach to work and parenting. Yet certain aspects of Swedish parental leave could also be responsible for the maintenance of (or even the increase in) health inequalities. Using a 'Health in All Policies' lens, this research project aims to assess the unintended health consequences of various components of Sweden's parental leave policy, including eligibility for and uptake of earnings based benefits.

Living arrangements after parental separation have minimal impact on mental health at age 7 years.

Methods: The study population included 39 661 children from the Danish National Birth Cohort, living in a nuclear family at age 6 months. Child mental health was measured at age 7 years with maternal reports of the Strength and Difficulties Questionnaire (SDQ) operationalised as a high total score.

Development level of the country of parental origin on dental caries in children of immigrant parents in Sweden.

Aim: To study the association of parental country of origin-expressed as low-, medium- and high-Human Development Index (HDI) countries-with caries experience in children of immigrant families in Stockholm.

Methods: This registry-based cohort study included all children born in 2000-2003 who resided in Stockholm County, Sweden, at age 3 years (n = 83,147) with follow-up at 7 years of age. A logistic regression was performed for the multivariate analysis with adjustments for socio-demographic factors.

Preterm disparities between foreign and Swedish born mothers depend on the method used to estimate gestational age. A Swedish population-based register study.

This study aims to examine whether disparities in gestational age outcomes between foreign and Swedish-born mothers are contingent on the measure used to estimate gestational age and, if so, to identify which maternal factors are associated with the discrepancy. Using population register data, we studied all singleton live births in Sweden from 1992-2012 (n = 1,317,265). Multinomial logistic regression was performed to compare gestational age outcomes classified into very (<32 weeks) and late preterm (32-36 weeks), term and post-term derived from the last menstrual period (LMP) and ultrasound estimates in foreign- and Swedish-born women.
